To all whom it may concern:

`Be it known that I, ROBERT E. HUNN, a citizen of the` United States, residing `at Oakland, in the county of Alameda `and `State of California, have invented new and useful Improvements in Lifters for Molded 4Objects, of whichthe following isa speciication.

ffiled February 18th,` 1913.

i The object of the present inventionis to provide an implement for rapidly and conit is formed, an article, having two parallel "inwardly or oppositely inclined flanges, such as a glass `tile like that shown in my appl1- cation for Letters Patent, Serial No. 749,169 The present methodof removing such a tile is to remove the mold :from the table onwhich it is sup-` ported, place above the tile a suitable support, invert the mold, by which inversion the tileis caused to rest on` the support, re-

move the mold upwardly therefrom, and` then remove the tile fromthe support on to a cooling plate. This operation necessitates the employment of two men, and occupies 1n the accompanyingdrawing, Figurel is a broken plan view showing the tile` 1n the mold and the implementin position ready to be applied thereto; Fig. 2 is an enlarged similar view showing `the implement applied to the tile and clampingits anges;

Fig. 3 is an enlarged cross sectional View on the line 3-3 of Fig. 2.

Referringto the drawing, 1 indicatesya handle, a portion 2 of which is reduced in i The handle is extended' at the outer end of the reduced portion into a body thickness.

3 having a narrow longitudinal central portion 4 in line with the handle, and outwardly flaring terminal portions 5, 6, the terminal portion 5 being that by which the body extends from the handle. On the bottom of said extension or body 3 is a rectan-` gular plate 7. Securedto, and extending from, the top of said terminalportion 5 `almost `at right angles to` the handle are plates 9.

On said terminal portion 6 and extending at right angles `to the handle is secured a plate 10, and "secured to the outer ends of the plates 9 and 10 and beneath the same are two parallel bars ,11, having `undercut inner edges.` Movable on said plate 7, and between said plate 7 and plates 9 and 10 are two blocks 13, 14,015` which theouter edges are normally parallel with the lbars` 11, and the inner edges normally extend in like directions with the adjacent edges ot the body 3. `To move said movable blocks there is` provided ailever 16pivoted, as

shown at 17, upon the terminal portion 5,

and arranged to move over Vthe reduced portion of the handle 1. Extendingfroin one end of said lever to one side thereof is a curved arm 18 pivoted, as shown at 19, to the block 13. On the same `end as the alim 18, but on the opposite side, there extends a short arm 2l. Upper and lower plates 22, 23 are secured upon said arms 18 and 21 and lever 1G. A` pvot 24 extends through said short arm 21 and plates 22, 23 and through two plates 26, secured on opposite sides of,

and extending from, a lever 27, pivoted on a i. stud or post 28 secured` to, and extending upwardly from, the plate `7 through a slot 29 `in the block" 14, the outerendbf said lever 27 being pivoted, as shown atw30,to said block 14. The outer straight edges of C said blocks 13 and 14 are beveled outwardly and downwardly or in "planes parallel with the inner undercut edges of the bars 11. A spring 31 is secured to the lever 16 and bears against a stop 32 `on the part .5, and a stop 33 on the handle limitsthe movement of `said lever.

In use, the outer end of the plate 7 is placed on the outer end of the mold `34, so that the spaces between the bars `11 and the outer edges of the blocks 13, 14, are in alinement with the respective flanges35 of the tile, 36, and then the implement is moved longitudinally in the direction parallel with said flanges, so that said flanges are in said spaces. The lever 17 vis then moved against v the force of the spring 31, so as to be in registry with the handle, which movement causes both` blocks 13, 14 to move outward, thus clamping the flanges of the tile respecl tively between the blocks 113, 14, and the bars 11.` The glass tile can then be raised from the mold by meansof said flanges.

When the tile has been placed upon a cooling plate, pressure iswithdrawn from the lever 16, whereupon the blocks are retracted from the bars by the action of the spring 31, and the implement can be slid backward from the tile. y For the reason that the blocks 13, lavare` moved toward the bars 11 with considerable` force, any irregularities accidentally i formed inthe flanges in the process of moldingare pressed out by said bars ,andl blocks.

it will be seen that with this implenie'nt one man can do the same work as two men` and in a small fraction of the time.

I Aclaim l. In an implement of the character described, the combination of a body, a handle therefor, side bars spaced from the body, supporting means for said side bars secured to 'the body, blocks movable on said body to and from the respective side bars, and having beveled outer edges, a lever movable in proximity to said handle, and operative connections between said lever and blocks whereby, with the movement of the lever in one direction, both of said blocks move outwardly, and, with the movement in the other direction, both blocks move inwardly.

2. In an implement of the character described, lthe combination of a body, a handle therefor, side bars spaced from the body, having undercut inner edges, blocks movable on said body to and from the respective side bars, and having beveled outer edges, a lever movable in proximity to said handle, 'and operative connections between said 'lever and blocks whereby,v with the movement of the lever in one direction, both of said blocks move outwardly, and, with the movement in the other direction, both blocks move inwardly.

In an implement of the character described, the combination of a body, a handle therefor., side bars spaced lfrom the body, supporting means for said side bars secured to the body, blocks movable on said body to :and from ythe respective side bars and H having beveled outer edges, a lever movable intoalinemeiit with said handle, a spring for returning said lever in the opposite direction, and operative connections between said leverand blocks whereby, with the iirst-namedmovement of the lever, both of the said body, and operative connections between said device and block whereby, by y the movement of the device ,inv one direction, both of said blocks move outwardly, and by its movement in they opposite direction both blocks move inwardly. y

5. The combination of a body, a handle therefor, a plate secured to the under side.

of said body, parallel sideJv bars, spaced from said body, and having undercut inner edges, supports secured tothe upper side'woil vsaid body, to the underside of which supports the vbars are secured,lblocks having beveled outer edges, and movable upon said plate and beneath said supports, a device movable on said body in opposite directions, and operative connections between said device and blocks whereby, by the movement of 'said device infone direction, said blocks are both moved outwardly, and, by its move- 'ment in 'the opposite direction, said blocks are both moved inwardly.

In testimony whereof I have hereunto vset `my hand inthe presence of two subscribing witnesses. n
